CTSS activation coexists with CD40 activation in human atheroma: evidence from plasma mRNA analysis

Clin Biochem. 2011 Apr;44(5-6):438-40. doi: 10.1016/j.clinbiochem.2011.01.003. Epub 2011 Jan 9.

Abstract

Objectives: By the analysis of plasma mRNA levels, we tested the hypothesis that, in human atheroma, CTSS activation coexists with activation of CD40.

Design and methods: mRNAs were isolated from plasma of patients with coronary atherosclerosis and quantified by real-time RT-PCR.

Results: CTSS mRNA levels correlated with CD40 mRNA levels, independently of observed traditional risk factors for atherosclerosis and pharmacological treatment.

Conclusions: Our results suggest that CTSS mediated atherogenesis may be associated with a CD40 mediated inflammatory and immune response. Further invasive atheroma analysis is reasonable.
